Amy Adams quietly did a cool thing on an airplane Friday -- and the world would have been none the wiser except for a tweet from another passenger outing the actress' wish-I'd-done-that-too goodness.

"Just saw actress Amy Adams do something incredibly classy. She gave her 1st class seat to an American soldier. I'm an even bigger fan now," wrote Jemele Hill, an ESPN personality who happens to have about a quarter-million Twitter followers.

The swap took place on a plane that was about to take off for L.A. out of Detroit, where parts of "Batman v Superman: Dawn of Justice" are being filmed. In the movie, 39-year-old Adams reprises her Lois Lane character opposite Henry Cavill's Clark Kent/Superman, with Jason Momoa, Gal Gadot, Ben Affleck and Jesse Eisenberg joining on as Aquaman, Wonder Woman, Batman and Lex Luthor, respectively.

"I noticed Ms. Adams was in first class and as I was getting seated, I saw the flight attendant guide the soldier to Ms. Adams' seat," Hill told ABC News.

The "American Hustle" star -- who acted "quietly and quickly," according to Hill -- met with the soldier briefly near the cockpit, post-swap, then she headed to coach. Back in the cheap seats, the five-time Oscar nominee posed for a couple of selfies with passengers Ernest Owens and a young woman whose Instagram shot was picked up by TMZ.
